I rebooted and 2nd display isn't recognized.

I have two nVidia 7950 GTX not in SLi. I'll call them A & B. I have two acer displays individually plugged into each one; X & Y. X into A; Y into B.

They were both working before I rebooted. I rebooted my system and during startup, A showed a lot of changing garbage on X that looked like old C64 blitter screens. I switched X to B and Y to A. X works with B. Y still receives no signal. In fact, in the windows 7 control panel > display, it only recognizes display X, of course. Suffice to say Y works with B too.

In the device manager it still shows I've got the two 7950's and they're working properly, it admits. I checked to see if drivers needed updating since I hadn't since installing Win7 64bit, but that changed nothing.

I feel A is toast, but I've never lost a card before. Is there any diagnostic tools that that I could use to see if card A is crap now? Or any other suggestions?

thanks,
Mord.

Try switching A into slot B and see if it makes a difference. If it does it may be some odd driver issue. Maybe your SLI bridge came loose? Oh I see you said not in SLi. Well my first idea is my only so far, see if you switch spots and the other one begins to post a signal.

Should probably remove everything but the problem card and see if it's still not working, sounds toast though.
